T() ALL WIIOM I'l MAY CONCERN:

Be it known that I, WILLIAn Porii-zuor, ot Brooklyn, in the county'otKings, and State of New York, have invented new and useful improvementsin Hernia Trusses, Abdominal Supporters, die.; and I do hereby decl-arc'that the following is a f'ull and exact description thereof, referencebeing had to the accompanying drawingsY and to the letters of referencemarked thereon.

Figure 1 is a view of a truss to which my improvements have beenattached.

Figgure 2, a detailed view of my device for regulating the pressure'ofthe body-spring.

Figure 3 is a detailed cross-section ofthe saine, taken through the linew w, fig. 1.

Figure 4 is a detailed sectional view of' the same, taken through theline y y, fig. 1.

Figure 5 is a detailed view illustrating a modification of the devicefor regulating the pressure of' the body-spring.

Figure 6 is a detailed sectional view ofthe same, taken through the line.e z, fig. 5.

`My inventionhas for its object to ,so improve the construction ofhernia trusses, abdomnal supporters, the., that the tension of' thebody-spring and the position of the pressure-pad may be regulated andadjusted at pleasure; and it consists, first, in the combination cfashoulder and adjustable bearing with a jointed `body-spring;`

second, a rotating slide or arm, to which the' pressure-pad is attached,fitted to a tubular socket, and secured in its place when adjusted by aset-screw; and, third, in a cut or slit at the end of such rotatingslideor arm, in which the end of the pad-spring is placed and may beturned, and is secured or clamped, when adjusted, hy means of aset-screw, the whole being constructed and operated as hereinafter morefully described,

A is the body-spring, to one end of which the back-pad B is attached inthe ordinary manner, and to the-` othcr end of which the pressurepad Cis connected. The spring A is jointed or hinged at its middle part, as

shown in figs. 1 and 6. To the spring A, upon one side of the joint orhinge, is riveted, or otherwise securely attached, a shoulder or block,D, the forward end of which is made concave, and is corrugated 4orgrooved, as shown in g. 2; and to the said spring A, on the other sideof said joint or hinge, is `pivoted a small eccentric, E, the edge ofwhich is grooved or milled, as shown in figs. 1 and 2, correspondingwith and fitted into the grooves in the concave end of the shoulder orblock D, as shown in fig. 2; By moving the ends of the spring towardseachother the eccentric E will be released from the shoulder D, and maybe turned, so as to present a longer or shorter radius towards the saidshoulder, according as it is desired lto increase or decrease thetension of' the a spring A. If desired, the forward end of' the shoulderD may be made square, and the eccentric Efmay he replaced with a block,F, having grooves or teelth upon its lower side fitting intocorrespondinggrooves or teeth' in the spring A, said "block beingsecured in place by a set-screw passing through a slot in the said blockand screwing into the said spring, as shown in figs. 5 and 6. Byloosening the said screw the block F may be moved closer to or furtherfrom the shoulder D, according as it is desired to increase or decreasethe tension of `the spring A. To the ends of the spring A, in front, isriveted, or otherwise attached, a cap, L, having aftubular socketextending underneath the spring, as shown in figs. 1 and 3, for thcpassage, revolution, and retentonof the rotating slide or arm I, whichis made of brass or other .suitable metal, and which. is held iu` place,when adjusted, by a set-screw screwing into the said cap L, with its endresting ou or pressing in to or against the said slide or arm I. Thisenables the said slide or arm I to be held securely in any position inwhich it may he placed to adjust thc position and pressure of the pad C.lhc slide or arm I may be grooved, and fitted to a groovcd socket, andsecured in place7 when adjusted, by the pressure ofr'a set-screw, but Iprefer to use a round bar, fnade of brass, and a steel-pointed screw.`lhe forward end of the arln I is slotted for the reception of the endof the padspring J, which, when adjusted, is secured or clamped in placeby the scrcwK, which passes throng-h the end of' the pad-spring J,forming a pivot, upon which the pad-spring may bc turned in the slot,and screws into the other part of' the said slotted arm I, which isfitted with a thread. The end of the arm I is cut or pared down on oneor both sides parallel `with the slot, the under partouly being fittedwith a thread, so that the slotted parts may he brought together bymeans of' thc screw K, and securely clamp the `end of the pad-spring-These devices allow the pad C to be so adjusted as to press in Vanyrequired direction, and with any desired degree of force, according tothe position and character of' the rupture. '.hc same devices m'ay beused in abdominal supporters, double trusses, and in any instrumentwhere it is desirable to vary und adjust the position of the pad or ofthe inward pressure of curvilinear spring at or near its extremities.

What I cieim as my invention, and desire to secure by Letters Patent,is-

1. The block or shoulder D und eccentric E, constructed :is describedfor 2. The rotating arm or slide I attached to one end of tbebodyadjusted, by a. eet-screw constructed and operating substuntiallyosan 3. The slotted end of the rotating amm I,- uscd in connection with asherein shown and described and for the purpose set forth.

The above specification of my invention-sgned by me this 11th doy ofMerch, A1867.
